Toxoplasma Infection Increases Risk Of Schizophrenia

Science Daily (Jan. 16, 2008) — Findings from what is believed to be the largest comparison of blood samples collected from healthy individuals and people with schizophrenia suggest that infection with the common Toxoplasma gondii parasite, carried by cats and farm animals, may increase the risk of schizophrenia.

History
The protozoan was first discovered by Nicolle & Manceaux, who in 1908 isolated it from the African rodent Ctenodactylusgundi, then in 1909 differentiated the disease from Leishmania and named it Toxoplasma gondii.[20] The first recorded congenital case was not until 1923, and the first adult case not until 1940.[20] In 1948, a serological dye test was created by Sabin & Feldman, which is now the standard basis for diagnostic tests.[37]
